Abstract
A vehicle approach alert device that outputs an approach report sound from a sounding body includes: a memory part in which data of the approach report sound is memorized; a signal generator that generates a voltage waveform signal of the approach report sound based on the data of the approach report sound; a calculator that calculates a temperature of the sounding body; and a correct part that corrects the approach report sound based on the temperature of the sounding body. The calculator acquires information about a temperature detected by a temperature sensor located at a position different from the sounding body in the vehicle, and estimates the temperature of the sounding body based on the temperature detected by the temperature sensor.
